FloMAX Fuel Nozzles connect to all standard fuel receivers. The FN600 fuel nozzle has latching dogs and the FNBL fuel nozzle uses a ball lock design. Both nozzles come with a ball bearing 1-1/2" NPT swivel and a plug, specially designed to seal out dirt and contaminants, attached with a PVC-coated 1/4" wire lanyard. A patent-pending removable piston assembly allows the cylinder to be easily removed for rebuilding. The standard shutoff pressure is set at 8.0PSI, however, FloMAX nozzles can be factory set from 5.5PSI shutoff to 13.0PSI as required. Both nozzles are 11" in length, weight 6.6lbs & have a rated working pressure of 125PSI. All flow path o-rings are viton while the sealing gaskets are nitrile rubber. Wiggins parts crossover avilable upon request.
